PURPOSE: In this research multi-level analysis was done to identify factors related to quality of services. Patient characteristics and organizational factors were considered. METHODS: The data were collected from the Health Insurance Review and Assessment Service (HIRA) data base. The sample was selected from 17,234 patients who had been admitted between January 2007 and May 2008 to one of 253 long-term care hospitals located in Seoul, six other metropolitan cities or nine provinces The data were analyzed with SAS 9.1 using multi-level analysis. RESULTS: The results indicated that individual level variables related to quality of service were age, cognitive ability, patient classification, and initial quality scores. The organizational level variables related to quality of service were ownership, number of beds, and turnover rate. The explanatory power of variables related to organizational level variances in quality of service was 23.72%. CONCLUSION: The results of this study indicate that differences in the quality of services were related to organizational factors. It is necessary to consider not only individual factors but also higher-level organizational factors such as nurse' welfare and facility standards if quality of service in long term care hospitals is to be improved.

Since the introduction of new health technology assessment in 2007, benefit coverage process of health insurance related to new health technology has become an upgraded system through the evidence-based decisions. As a result of enforcing this system for 10 years, however, there have been several rising concerns. It needs to support the insufficient evidence of medical technologies, introduce reassessment system for post management of market entry technologies, and improve evaluation methods and process. In addition, there is the possibility of emerging an unheard-of medical technology, fused various categories like artificial intelligence, robot, information technology, physics and life science in the fourth industrial revolution. Now, new updated system introduced to improve new technology assessment, such as ‘limited health technology assessment system,’ ‘system for postponement of new health technology assessment,’ ‘one-stop service system,’ and ‘integrated operation of approval for medical devices and new health technology assessment.’ Therefore it needs to prepare the improvement plan for new health technology assessment to be established more advanced system, and we have to resolve concerns by communication with various healthcare experts and patients now and for ever.

PURPOSE: Robotic surgery (RS) overcomes the limitations of previous conventional laparoscopic surgery (CLS). Although meta-analyses have been published recently, our study evaluated the latest comparative surgical, urologic, and sexual results for rectal cancer and compares RS with CLS in patients with rectal cancer only. METHODS: We searched three foreign databases (Ovid-MEDLINE, Ovid-Embase, and Cochrane Library) and five Korean databases (KoreaMed, KMbase, KISS, RISS, and KisTi) during July 2013. The Cochrane Risk of Bias and the Methodological Index for Non-Randomized were utilized to evaluate quality of study. Dichotomous variables were pooled using the risk ratio (RR), and continuous variables were pooled using the mean difference (MD). All meta-analyses were conducted with Review Manager, V. 5.3. RESULTS: Seventeen studies involving 2,224 patients were included. RS was associated with a lower rate of intraoperative conversion than that of CLS (RR, 0.28; 95% confidence interval [CI], 0.15-0.54). Time to first flatus was short (MD, -0.13; 95% CI, -0.25 to -0.01). Operating time was longer for RS than that for CLS (MD, 49.97; 95% CI, 20.43-79.52, I2 = 97%). International Prostate Symptom Score scores at 3 months better RS than CLS (MD, -2.90; 95% CI, -5.31 to -0.48, I2 = 0%). International Index of Erectile Function scores showed better improvement at 3 months (MD, -2.82; 95% CI, -4.78 to -0.87, I2 = 37%) and 6 months (MD, -2.15; 95% CI, -4.08 to -0.22, I2 = 0%). CONCLUSION: RS appears to be an effective alternative to CLS with a lower conversion rate to open surgery, a shorter time to first flatus and better recovery in voiding and sexual function. RS could enhance postoperative recovery in patients with rectal cancer.

BACKGROUND: The purpose of this study was to evaluate the effectiveness of Xpert MTB/RIF (Cepheid, USA) in the detection of Mycobacterium tuberculosis and to determine rifampin resistance. METHODS: The literature review covered the period from 16 August 2011 to 1 October 2011, and eight domestic databases and foreign databases including Ovid-Medline, Embase, and Cochrane Library were used. Key words, such as 'Rifampin, Polymerase Chain Reaction,' 'GeneXpert' and 'Xpert MTB-RIF' were used to search a total of 1,385 documents. The SIGN (Scottish Intercollegiate Guidelines Network) tool was used to evaluate the quality of the 20 selected studies. RESULTS: Test accuracy for the detection of M. tuberculosis was assessed on the basis of 20 studies using the M. tuberculosis culture test as the reference standard. The acid-fast bacteria smearing test had a sensitivity in the range of 0.69-1.00, specificity in the range of 0.72-1.00 and test accuracy in the range of 0.75-1.00. Test accuracy regarding rifampin resistance was assessed on the basis of 17 studies. Using an anti-tuberculosis agent sensitivity test as the reference standard, the sensitivity, specificity and test accuracy of real-time, nested PCR were in the ranges of 0.75-1.00, 0.96-1.00 and 0.95-1.00, respectively. CONCLUSION: Xpert MTB/RIF is a useful test for patients suspected of having rifampin-resistant tuberculosis.

PURPOSE: Reports from several case series have described the feasibility and safety of robotic surgery (RS) for colonic cancer. Experience is still limited in robotic colonic surgery, and a few meta-analysis has been conducted to integrate the results for colon cancer specifically. We conducted a systematic review of the available evidence comparing the surgical safety and efficacy of RS with that of conventional laparoscopic surgery (CLS) for colonic cancer. METHODS: We searched English databases (MEDLINE, Embase, and Cochrane Library), and Korean databases (KoreaMed, KMbase, KISS, RISS, and KisTi). Dichotomous variables were pooled using the risk ratio, and continuous variables were pooled using the mean difference (MD). RESULTS: The present study found that the RS group had a shorter time to resumption of a regular diet (MD, -0.62 days; 95% CI, -0.97 to -0.28), first passage of flatus (MD, -0.44 days; 95% CI, -0.66 to -0.23) and defecation (MD, -0.62 days; 95% CI, -0.77 to -0.47). Also, RS was associated with a shorter hospital stay (MD, -0.69 days; 95% CI, -1.12 to -0.26), a lower estimated blood loss (MD, -19.49 mL; 95% CI, -27.10 to -11.89) and a longer proximal margin (MD, 2.29 cm; 95% CI, 1.11-3.47). However, RS was associated with a longer surgery time (MD, 51.00 minutes; 95% CI, 39.38-62.62). CONCLUSION: We found that the potential benefits of perioperative and short-term outcomes for RS than for CLS. For a more accurate understanding of RS for colonic cancer patients, robust comparative studies and randomized clinical trials are required.

Purpose: This study aimed to evaluate the cost-effectiveness of treatment with retrograde intrarenal surgery (RIRS) versus repeated shock wave lithotripsy (SWL) in patients with renal calculi. Materials and Methods: The non-retreatment rates (NRRs) and their respective real-world costs for RIRS and SWL were derived through retrospective analysis of health insurance claims data from 2015 to 2017. Decision tree modeling was performed to demonstrate the cost-effectiveness of RIRS. Furthermore, sensitivity analysis was performed to examine the robustness of the results. Results: Analysis of the obtained data showed that NRRs of single SWL ranged from 46% to 56%, whereas NRRs of single RIRS ranged from 75% to 93%. Introducing RIRS early in the treatment sequence was observed to be favorable for the reduction of overall failure (overall NRR, 0.997) compared to the results of repeated SWL (overall NRR, 0.928). The implementation of decision tree modeling revealed that the cost per retreatment-avoided increased with the introduction of RIRS at an earlier time (first line, second line, third line, fourth line: 18640 USD, 10376 USD, 4294 USD, 3377 USD, respectively). Probabilistic modeling also indicated that the introduction of RIRS as the first line of treatment was least likely to be cost-effective, when compared to other options of introducing RIRS as the second, third, or fourth line of treatment. Conclusion Performing RIRS as early as possible

PURPOSE: To systematically update evidence on the clinical efficacy and safety of robot-assisted radical prostatectomy (RARP) versus retropubic radical prostatectomy (RRP) in patients with prostate cancer. MATERIALS AND METHODS: Electronic databases, including ovidMEDLINE, ovidEMBASE, the Cochrane Library, KoreaMed, KMbase, and others, were searched, collecting data from January 1980 to August 2013. The quality of selected systematic reviews was assessed using the revised assessment of multiple systematic reviews and the modified Cochrane Risk of Bias tool for non-randomized studies. RESULTS: A total of 61 studies were included, including 38 from two previous systematic reviews rated as best available evidence and 23 additional studies that were more recent. There were no randomized controlled trials. Regarding safety, the risk of complications was lower for RARP than for RRP. Among functional outcomes, the risk of urinary incontinence was lower and potency rate was significantly higher for RARP than for RRP. Regarding oncologic outcomes, positive margin rates were comparable between groups, and although biochemical recurrence (BCR) rates were lower for RARP than for RRP, recurrence-free survival was similar after long-term follow up. CONCLUSION: RARP might be favorable to RRP in regards to post-operative complications, peri-operative outcomes, and functional outcomes. Positive margin and BCR rates were comparable between the two procedures. As most of studies were of low quality, the results presented should be interpreted with caution, and further high quality studies controlling for selection, confounding, and selective reporting biases with longer-term follow-up are needed to determine the clinical efficacy and safety of RARP.

PURPOSE: Systematic studies on the relationship between health literacy and health outcomes demonstrate that as health literacy declines, patients engage in fewer preventive health and self-care behaviors and have worse disease-related knowledge. The purpose of this study was to identify effective intervention strategies to improve health outcomes in patients with cardiovascular disease and low literacy skills. METHODS: This study employs the following criteria recommended by Khan Kunz, Keijnen, and Antes (2003) for systematic review: framing question, identifying relevant literature, assessing quality of the literature, summarizing the evidence, and interpreting the finding. A total of 235 articles were reviewed by the research team, and 9 articles met inclusion criteria. Although nine studies were reviewed for their health outcomes, only six studies, which had a positive quality grade evaluation were used to recommend effective intervention strategies. RESULTS: Interventions were categorized into three groups: tailored counseling, self-monitoring, and periodic reminder. The main strategies used to improve health outcomes of low literacy patients included tailored counseling, improved provider-patient interactions, organizing information by patient preference, self-care algorithms, and self-directed learning. Specific strategies included written materials tailored to appropriate reading levels, materials using plain language, emphasizing key points with large font size, and using visual items such as icons or color codes. CONCLUSION: With evidence-driven strategies, health care professionals can use tailored interventions to provide better health education and counseling that meets patient needs and improves health outcomes.

Toxic epidermal necrolysis (T~EN) is a severe mucocutaneous disease characterized by epidermal necrosis possibly extended to the entire body surface and involving multiple internal organs. Digestive tract may be involved too, but there is few report about gastrointestinal lesion in patient with TEN. Recently we experienced a case of TEN with gastrointestinal bleeding in previously healthy 32-year-old woman. The condition developed three days after the initiation of treatment with NSAID and progressed caudally, involving 60 percent of the skin surfaces. During a period of admission gastrointestinal bleeding was noticed. The gastrofiberscopy showed diffuse superficial mucosal lesion with oozing from swollen friable and erythematous mucosa. The skin lesion was progressed inspite of withdrawal of causative agents. The patient was expired due to combined septic shock 10 days later. We report this case with gastrofiberscopic findings and a brief review of literature.

BACKGROUND: Robotic surgery is an alternative to minimally invasive surgery. The aim of this study was to report on current trends in robotic thoracic and cardiovascular surgical techniques in Korea. METHODS: Data from the National Evidence-based Healthcare Collaborating Agency (NECA) between January 2006 and June 2012 were used in this study, including a total of 932 cases of robotic surgeries reported to NECA. The annual trends in the case volume, indications for robotic surgery, and distribution by hospitals and surgeons were analyzed in this study. RESULTS: Of the 932 cases, 591 (63%) were thoracic operations and 340 (37%) were cardiac operations. The case number increased explosively in 2007 and 2008. However, the rate of increase regained a steady state after 2011. The main indications for robotic thoracic surgery were pulmonary disease (n=271, 46%), esophageal disease (n=199, 34%), and mediastinal disease (n=117, 20%). The main indications for robotic cardiac surgery were valvular heart disease (n=228, 67%), atrial septal defect (n=79, 23%), and cardiac myxoma (n=27, 8%). Robotic thoracic and cardiovascular surgeries were performed in 19 hospitals. Three large volume hospitals performed 94% of the case volume of robotic cardiac surgery and 74% of robotic thoracic surgery. Centralization of robotic operation was significantly (p<0.0001) more common in cardiac surgery than in thoracic surgery. A total of 39 surgeons performed robotic surgeries. However, only 27% of cardiac surgeons and 23% of thoracic surgeons performed more than 10 cases of robotic surgery. CONCLUSION: Trend analysis of robotic and cardiovascular operations demonstrated a gradual increase in the surgical volume in Korea. Meanwhile, centralization of surgical cases toward specific surgeons in specific hospitals was observed.
